How Do You Know It’s Time to Replace?
Tankless water heaters are like the marathon runners of home appliances. They are built to last and work hard for years, but even the best eventually slow down. The key is knowing when your system is hinting that it is ready to retire so you can replace it before it leaves you in the cold.
Here are some signs it might be time for a tankless water heater replacement:
- Water is not heating up like it used to. If your once-piping-hot showers are now just “warmish,” your system may be losing efficiency.
- Frequent error codes. If your display panel is suddenly lighting up like a slot machine, it could mean bigger problems are on the horizon.
- Unusual noises. A quiet hum is normal, but loud clicks, bangs, or buzzing can be a red flag.
- Visible corrosion or leaks. Even small drips can cause major water damage over time.
- Age. Tankless units can last 15 to 20 years with good maintenance. If yours is getting close, start thinking about replacement.

Waiting too long for a tankless water heater replacement can lead to more than just a few chilly mornings. You could end up with water damage to floors, walls, or cabinetry, higher energy bills from an inefficient system, and the joy of an emergency replacement at the worst possible moment.
When you call Polly Plumbing, we will take a close look at your system, explain what we find in plain English, and help you decide whether a tankless water heater repair will keep things going or if it is smarter to upgrade now. We will walk you through options for a tankless water heater replacement that fits your home and your budget, then handle the installation from start to finish.

How much would it cost to change to a tankless water heater?
Making the switch can be as low as $2,995 (owner supplied), but may cost more depending on the model and the installation circumstances. The exact number depends on the size of the heater you pick and whether your home’s gas or electrical setup needs a little TLC first. Think of it as an upgrade that pays you back in endless hot showers and lower energy bills.
How often do tankless water heaters need to be replaced?
The beauty of going tankless is longevity. Most units last 15 to 20 years with good maintenance—nearly twice as long as the old-school tank version. Once yours starts creeping up on that age, it’s time to start planning for the next one.
Is it worth replacing a tank water heater with a tankless?
If you’re tired of racing your family to the shower before the hot water runs out, a tankless is a game-changer. They’re more efficient, take up less space, and keep the hot water flowing as long as you need it. Yes, the upfront price is higher—but most folks find it totally worth it.
Is it difficult to replace a tankless water heater?
For you? Yes. For a pro? Not so much. Swapping one out involves plumbing, gas, and sometimes electrical work, so it’s not exactly a weekend DIY project. But once a licensed plumber handles it, you’ll be set for years of cozy showers.
Do you need a plumber to install a tankless water heater?
Yep! A licensed plumber makes sure everything is hooked up safely and up to code. Sometimes an electrician joins the fun too, depending on your setup. That way, you get peace of mind knowing your hot water is good to go.
